This invention has for its objectto furnish an imp! cred" machfiir'eutting roli papeato on rrvat -their cit-ten ends: be used astelegraph-paper, ribbon-pape1',hatbinding, and for other purposes, themachine "accomplishing the cutting of a number, of strips at thesame'time,'and thewinding up 'ofthesame-iu a superior andefl'ectivexmanneron the same shaft. 4 -Tlic invention consists of'anoscillating frame withguide-rollsfor the continuous paper', that isunwound from a shaft at one end of-tlie machine, andwoun'd-up'on arevolving shaft at theotherend, being-cut into as many strips asrequired by setsof disk-shaped knives, turning by elasticfriction-pulleys on "the endsof adjustable arms of fixed cross- 'bars-ofthe oscillating-frame. To the oscillating frame is'attached, at asuitable angle, a supplementary frame with guide-rolls, of which thelowermost roll bears on the strips windin g up on the revolving shaft,so as to produce their tight rolling up, in connection with adjustahletension devices. To a cross-bar of the oscillating frame isapplied,below the paper to be cut, a number of adjustable fingers,

that divide the strips and secure their separate winding'up on therevolving shaft. The unudndingshaftis set laterally by means of ahand-lever, and the shaft provided withja weighted friction-lever,spring, or other brake,

The cutting' knives are made .fo d sk slut with sharpedges, that passsligh tlyone be the otlier, so as-to cut the paperjfedthroi between thesame. j L j 1 Adjoining the disk-shaped knives 'arefarf ranged on thesame shafts irictionrpu lleysrl f leather, felting, or other material,"htormg contact with both'sides of the paper through between the sameaud'the kn es sog as to cause the continuous/revolving the; knivesandaclear' shear-cut on thel m 7 without any danger or possibility ofthe: te ingot thepaper. pf

,Anynu'mber of sets of cutting-l nives-, ma bearranged at suitabledistances on the crossbars of the oscillating frame B,and'adjustedthereon accord n'g to the number and width of the strips to be out. a

When the machine isprepared for work the clamp-screws d of theknife-supporting arms E are loosened, and the knives so adjusted thatthey lap at one point of ,their circumference ,over each other, and thatthe friction-. pulleys of their shafts work with suflicientpressure" onthe-paper to cause the reliable revolving and cutting of the knives.' Atthe same side of the oscillating frame on which the knives areal-rangedis attached, at suitable angle thereto, a supplementary frame, B, withtop, bottom, and intermediate guide-rolls, over which the paper to be.cut is passed before being acted upon. by the knives, and finallyconducted over the'lojwer roll to the windingup shaft D a a v settersThelower roll of the supplementary frame .13 bears on -'thestrips ofrollpaper as they windup on the shaft D, so as to prodnce their tightwinding up and the raising of the oscil- .lating frame and knives astherolls'incrcase in diameter. s 1 .,-f

e As the cutting-knives revolve by the frictioii with the paper drawnthrough the machine by.

the winding-up shaft, their'action corresponds always to the 'speed'ofithe winding-up shaft, withoi t the objectionable features of a separategear and positive motion. The close proximity of the cutting-knives tothe winding-up' shaft, together with the action of the' lowerpressure-roll of the supplementary frame, prodnces the tight winding upof the strips of paper in uniform manner on one and the same shaft,without the'diflicnlties which were heretofore experienced by thevarying speeds of thedifi'ercnt winding-up shafts used inroll-paper-cntting machines. The tension of the paper drawn through themachine is regulated bya friction-disk and brake arrangement oftheunwinding-shaft G, the brake being either a weighted, lever,spring-band, or any other.

oscillating frame, so that the 'rolls may be wound up more or lesstight, as required for the purpose for which they are intended. To

the oscillating frame B is also attacheda fixed cross-bar, F, that"extends bel ow theknives,

and is 7 provided with as many adjustable. finge-s F as there are setsof cutting-knives used in the machine. These fingers enter between thestrips as they are severed by the knives, so as to separate them andprevent any possibility of their lapping over each other or gettingentangled withthe adjoining rolls.

The entire series of strips is thus woun 5 up on 7 one shaft with anydesired degree of tightness, and cut in uniform and rapid manner bymeansof a comparatively simple construction of cuttingvmachine.

As an improvement. inroll-paper-cntting machines, vthe combination of the oscillatin' g 1frame, having web guidevrolls and sets of adjustable cutting-knives,with an unwindingshaftat one sidek/a-nd a winding-up sha-ft at the otherside of t 1e fulcrum of the oscillating frame, substantially as and forthe, purpose described.

2. The combination of the oscillating frame, having sets ofcutting-knives and a fixed supplementary frame, with guide and pressurerolls, with an nnwinding-shaftat one end and a winding-up shaft at theopposite end of the machine, substantially as specified.

3. .In a roll-paper-cntting machine, the combination of the oscillatingframe, having crossbars, .with laterally-adjnstable supports or arms,having fixed shafts, with revolving friction-pniieys and cutting-knives,substantially as and for-thepurpose set forth; V

4. The combination of the oscillatingfi'ame,

having adjustable cutting-knives and frictionpull'cys, and asupplementary frame with contiguous guide and .pressnrerolls, with annnwinding-shaft, having suitable tension devices, and with a windingupshaft, substantially as specified.
